BT-PGER Collet Chuck Holder delivers a clamping precision (runout) of ≤0.003mm and twice the clamping force of standard ER collet chucks. A full-round nut lowers windage and vibration, while an optimized structure provides built-in damping that extends spindle service life, and the precision 30° trapezoidal thread locks smoothly and securely. Made from high-performance alloy steel with -195°C gas-method cryogenic treatment for enhanced hardness, strength, dimensional accuracy, wear, impact and corrosion resistance, and dynamically balanced up to 30,000 RPM. Built to the JIS MAS 403 BT spindle taper standard across the full BT30 / BT40 / BT50 shank range. Uses standard ER collets with no proprietary tooling.
